Log your sessions; that is how Windulu gets to know you.
The advice is a tool. You remain responsible for your own safety.
Castricum aan Zee is the quieter alternative between Wijk aan Zee and Zandvoort: the same wide North Sea beach and the same waves, but less traffic on the water. A fine spot to clock up some undisturbed miles when the better-known neighbours are packed.
The open water at Castricum aan Zee faces WNW (290°). The safest wind directions to get on the water here are north, southwest, west and northwest (onshore or cross-onshore). With the wind from the northeast and south, it runs cross to cross-offshore: doable, but mind your position and don't go alone. With the wind from the east and southeast, it blows offshore and is dangerous: you'll be pushed off the beach onto open water (no-go).
